Sony PlayStation (PS1): The Grey Machine That Grew Up With Us

In short

In 1994 a consumer electronics company with no console history walked into a market owned by Nintendo and Sega and, within a few years, took it over. The original PlayStation turned gaming into a mainstream pastime for teenagers and adults, and made CDs the standard for games.

Fun fact: The PlayStation's CPU clock of 33.8688 MHz isn't a random number. It's exactly 768 times 44.1 kHz, the sample rate of an audio CD.

The full story

The US price became legendary: at the 1995 E3 show, Sega announced the Saturn at $399, and Sony's representative simply walked on stage, said "$299" and walked off again.

The origin story is just as famous. The PlayStation grew out of an abandoned collaboration between Sony and Nintendo on a CD add-on for the SNES. When that deal collapsed, Sony carried on alone.

Key games

Cheap CD manufacturing and friendly terms for developers meant the PlayStation attracted an enormous range of publishers, from huge Japanese studios to small European teams.

Sales and legacy

Sony's official figures show that the PlayStation and its slimmed-down PS one model reached 102.49 million cumulative worldwide shipments, with 21.59 million in Japan and Asia, 40.78 million in North America and 40.12 million in Europe/PAL. It was the first console to pass 100 million units, a milestone Sony announced in May 2004. Sony's current business data rounds the total to "more than 102.4 million".

The PS one, a smaller redesign launched in 2000, accounted for around 28 million of those units.

The legacy is enormous. The PlayStation confirmed 3D as the new normal, popularised the memory card, and with the DualShock pad (1997) made dual analogue sticks and rumble essential. Most importantly, it changed the image of gaming in the UK, from bedroom hobby to something advertised in nightclubs and played by people in their twenties.

Sony's PlayStation Classic mini console (2018) was less loved than Nintendo's minis, but many PS1 games are available again through PlayStation Plus Premium.

Buying tips

Where to buy now

Original hardware is still easy to find second-hand, but condition varies wildly. Check that a console has been tested, look closely at photos of ports and cartridge slots, and remember that a reputable retro shop will usually offer a short warranty that a private seller won't.
